MOPED ARMY

thats what gives your spark plug it spark, look on the wiki, there are wiring diagrams there.

1. Black box is high voltage ignition coil (Bosch)

2. Yes, if ignition coil is not connected, you get no spark & engine does not start.

Bosch high voltage ignition coil needs both spade terminals connected to it.

- One spade terminal goes to magneto points/condenser (Sachs blue wire usually)

- 2nd spade terminal goes to ground which can be frame of moped or outside engine (Sachs brown wire usually)

3. If that hanging Blue wire is from stator magneto points/condenser, then that should connect to spade terminal on Bosch ignition coil.
